This study uses a recently developed firm-level measure of credit constraints for 111 countries from the World Bank Enterprise Surveys to analyze the role of credit information in firms’ access to finance. The new data classifies firms in four categories according to their access to finance from least to most credit constrained. The findings of regression analyses show that small and medium size firms are more likely to be credit constrained. In addition, a more advanced credit information system is associated with lower levels of credit constraints particularly for smaller firms, firms that are not externally audited or do not have a quality certification. These findings confirm the results of previous studies that have used firms’ perceptions of financial obstacles to measure financial access.
